The discovery and optimization of non-nucleoside dengue viral RNA-dependent-RNA polymerase (RdRp) inhibitors are described. An X-ray-based fragment screen of Novartis’ fragment collection resulted in the identification of a biphenyl acetic acid fragment 3, which bound in the palm subdomain of RdRp. Subsequent optimization of the fragment hit 3, relying on structure-based design, resulted in a >1000-fold
Described herein is the DP

antagonist [2′-(3-benzyl-1-ethyl-ureidomethyl)-6-methoxy-4′-trifluoromethyl-biphenyl-3-yl]-acetic acid, or a pharmaceutically acceptable salt thereof. Also described are methods of preparing the DP2 antagonist, or a pharmaceutically acceptable salt thereof. Also described herein are pharmaceutical compositions suitable for administration to a mammal that include the DP
